I linked a MySQL table into an OracleXE database (Short How to) and discovered a really strange behavior. When I tried an usual select about the MySQL table from my sqlplus client an error occurred: ORA-00904: "last_name": Invalid identifier

Why German? I come from and live in Germany! ;DI haven't really provided lot's of APEX based information in German. This just has to change. What to do?Last year I created a small Oracle monitoring application with APEX and ExtJS. It was developed to collect CPU, Tablespace, Init.ora, Session and even more information about Oracle databases. In combination with some other monitoring tools it was quite a good (cheap) alternative to some expensive tools.

If you want to send data from your APEX application to an external website (like PHP) through the POST method. You can use the following example:Add a new page (in my example it's page number 2)

Add a new button on the page where you want to send data from: BTN_SEND_DATE With the following options:Target is a: URLURL Target: javascript:void(window.open('f?p=&APP_ID.:2:&SESSION.:::::', 'popup', 'toolbar=no,width=1024,height=768, resizable=yes,top=40,scrollbars=yes'));On page 2: Add your variables1 P2_ID Hidden -- Needs to be set before page load2 T_NAME Hidden 3 T_DESC Hidden3 T_USER Hidden....Set variable P2_ID before you open page 2
